Effect: The human being with supernatural abilities asks the folks, "Wanna see something strange?" They say they would like that very much. "Well, it's gonna cost ya five...no, TEN bucks. Plus tax. That would normally work out to over 11 dollars, but let's just keep it simple. To show you something you're going to remember for the rest of your lives I'm going to need 10 bucks and 10 cents. Whose got a 10 dollar bill and a dime?"
The spectators cough up the cash and -without ever touching the coin- Mr. Magic asks someone to place the dime on the ten dollar bill and crunch the bill into a tight ball. The magician hands someone a pen and asks them to get ready to write something down on whatever is handy (paper napkin, business card, etc.) With his eyes closed and head turned away, the magician holds the balled up bill in his hand and focuses his considerable psychic energy on the coin nestled in the bill. "I'm getting a sense that the coin is...silver, right?" The audience is nonastonished.
